Found and fixed another oil leak on my 2180 VW. I had replaced the external oil cooler from Great planes and installed the Revmaster oil cooler and pump. The leak was on the Revmaster oil pump housing; the oil pressure regulator adjustment screw has a gland nut to lock the adjustment screw in place. I tightened the gland nut to squeeze the fiber washer a little tighter. This fixed leak number 8; hopefully no more oil smoke and drips. In fairness to Great plains and Revmaster, all of the oil leaks have been due to my installation errors.
